Aiming at the problem of the integration of cab safety and sense of safety, the research on the integration of cab shape structure safety is carried out. Firstly, the relationship among shape, function, and structure design is analyzed, and the safety fusion model of shape structure is proposed. Secondly, according to the safety standard of the cab, the finite element modeling and analysis of the cab are carried out. Finally, the influence of structure size on the cab is analyzed. The results show that: since the safety of the cab is not sensitive to the length, width, and height of the structural dimensions, once the structural design of the cab meets the safety requirements, the length, width, and height of the structural dimensions of the cab can be appropriately adjusted to improve the safety and comfort of drivers and passengers.
The analysis of product image modeling is the premise of designing new style modeling. This paper proposes a modeling and analysis method of product image modeling based on multi-objective decision-making. Firstly, the product image modeling design is analyzed, and the modeling method of product image modeling style is proposed based on the non-inferior solution of multi-objective decision-making in terms of maximum and minimum objectives. Then, taking the mining vehicle as the object, using the semantic differential method and image scale method, a questionnaire survey on the safety image of the mining vehicle was carried out, and obtain image scores of 12 mining vehicles were. Finally, the principal component analysis method is applied to build mining vehicles' safety image modeling style model from the two dimensions of safety connotation and artistic conception. The research provides a new way for the cognitive analysis of product image modeling style and enriches the theory and methodology of product image modeling design.
